"About a week ago I had a sick goldfish in my tank...he had white spots all over him, and was frequently at the top of the tank. I did my research and discovered it was a fungus, and quickly did my homework on the type of medicine to use.
After reading the other ratings, I decided to give this a try in conjunction with Melafix and a pinch of aquarium salt. It started working within the first hour of adding it to a separate tank with the sick goldfish. I am happy to say that the fish is now swimming around a lot better, and eating habits have improved also. I would definitely recommend this product...it was money (very) well spent!!"
